[0044] As Figure 1 shown is a working flowchart of a computer room control method according to an embodiment of the present invention, including:
[0045] Step S101, determining the independent or coupled operation of the ground source heat pump system, boiler heating system, and refrigeration system of the computer room according to the overall refrigeration heat release and heating heat absorption of the computer room;
[0046] Step S102, when the ground source heat pump system operates independently, match the number of cold and heat units of the ground source heat pump system according to the cooling and heating demands, and turn on the cold and heat units with the matched number of cold and heat units.
[0047] Step S103, when the refrigeration system operates independently, match the number of refrigeration units of the refrigeration system according to the cooling load demand, and turn on the refrigeration units with the matched number of refrigeration units.
[0048] Specifically, the present invention can be applied to an electronic device with processing capabilities.
[0049] First, execute Step S101 to determine whether to operate the ground source heat pump system, boiler heating system, and refrigeration system of the computer room independently or in a coupled manner according to the overall cooling and heat release, and heating and heat absorption of the computer room.
[0050] Specifically, the energy supply system of the computer room includes: a ground source heat pump system, a refrigeration system, and a boiler heating system. In the ground source heat pump system, 1 ground source heat pump + unit waterway electric valve + 1 user-side circulation pump + 1 ground source-side circulation pump are defined as 1 set of cold and heat units. In the boiler heating system, 1 boiler + unit waterway electric valve + 1 user-side circulation pump are defined as 1 set of boiler heating units. In the refrigeration system, 1 refrigeration unit + unit waterway electric valve + 1 user-side circulation pump + 1 cooling-side circulation pump + 1 cooling cooling tower are defined as 1 set of cold and heat units.
[0051] The system has two modes: heating and cooling. The ground source heat pump system and the boiler heating system are used in the heating mode, and the ground source heat pump system and the refrigeration system are used in the cooling mode. According to the hourly load calculation results of HVAC throughout the year, the ground source heat release value during refrigeration and the ground source heat absorption value during heating of the ground source heat pump system are known.
[0052] Therefore, according to the comparison relationship between the overall cooling and heat release, and heating and heat absorption of the computer room, determine how to use the ground source heat pump system, boiler heating system, and refrigeration system.
[0053] Then, if it is determined that the ground source heat pump system operates independently, then execute Step S102 to match the number of cold and heat units of the ground source heat pump system according to the cooling and heating demands, and turn on the cold and heat units with the matched number of cold and heat units. If it is determined that the refrigeration system operates independently, then execute Step S103 to match the number of refrigeration units of the refrigeration system according to the cooling load demand, and turn on the refrigeration units with the matched number of refrigeration units.
[0054] The present invention determines to independently or coupledly operate the ground source heat pump system, boiler heating system, and refrigeration system of the computer room according to the overall refrigeration heat release and heating heat absorption of the computer room, so as to realize the coordinated management of multiple energy supply systems. At the same time, when the ground source heat pump system operates independently, the number of cold and heat units of the ground source heat pump system is matched according to the cold and heat demands, and the cold and heat units with the number of started cold and heat units are started. When the refrigeration system operates independently, the number of refrigeration units of the refrigeration system is matched according to the cooling load demand, and the refrigeration units with the number of started refrigeration units are started. Therefore, the energy consumption of the present invention can avoid wasting energy by starting too many units while meeting the system requirements.
[0055] As Figure 2 shown is a working flowchart of a computer room control method in another embodiment of the present invention, including:
[0056] Step S201, when the refrigeration heat release is greater than the heating heat absorption, then in winter heating, the ground source heat pump system is preferentially used to operate independently for heating. When the heat load of the ground source heat pump system cannot meet the system load demand, the boiler heating system is enabled to operate in coupling with the ground source heat pump system for heating. In summer refrigeration, the ground source heat pump system and the refrigeration system are used to operate in coupling for refrigeration;
[0057] When the refrigeration heat release is less than the heating heat absorption, then in summer refrigeration, the ground source heat pump system is preferentially used to operate independently for heating. When the cooling load of the ground source heat pump system cannot meet the system load demand, the refrigeration system is enabled to operate in coupling with the ground source heat pump system for refrigeration. In winter heating, the ground source heat pump system and the boiler heating system are used to operate in coupling for heating.
[0058] Step S202, when the ground source heat pump system operates independently, obtain the corresponding relationship between the unit load rate and the energy consumption ratio of the cold and heat units of the ground source heat pump system; calculate the unit load rate corresponding to each opening number according to the cold and heat demands; according to the corresponding relationship, calculate the energy consumption ratio corresponding to the unit load rate corresponding to each opening number, and select the opening number corresponding to the unit load rate with the largest energy consumption ratio as the number of started cold and heat units of the ground source heat pump system.
[0059] In one embodiment, the calculating the unit load rate corresponding to each opening number according to the cold and heat demands includes:
[0060] According to historical data, predict the average cold and heat power prediction value within a preset time period;
[0061] Calculate the unit load rate corresponding to each opening number as: Bi = EMRQ 冷热 / (i * EMR 额), where Bi is the unit load factor corresponding to the opening number i, and EMRQ 冷热 is the predicted value of the average cooling and heating power, i is the opening number, and EMR 额 is the rated power of a single cooling and heating unit. When Bi > 1, set Bi = 0.
[0062] Step S203: Turn on the cooling and heating units with the number of cooling and heating units turned on.
[0063] Step S204: When the refrigeration system operates independently, obtain the corresponding relationship between the unit load factor and the energy consumption ratio of the refrigeration units of the refrigeration system; calculate the unit load factor corresponding to each opening number according to the cooling load demand; according to the corresponding relationship, calculate the energy consumption ratio corresponding to the unit load factor corresponding to each opening number, and select the opening number corresponding to the unit load factor with the largest energy consumption ratio as the number of refrigeration units turned on for the refrigeration system.
[0064] In one embodiment, the calculating the unit load factor corresponding to each opening number according to the cooling load demand includes:
[0065] Predict the predicted value of the average cooling power within a preset time period according to historical data;
[0066] Calculate the unit load factor corresponding to each opening number as: Ci = EMRQ 冷 / (i * EMR 额 ), where Ci is the unit load factor corresponding to the opening number i, EMRQ 冷 is the predicted value of the average cooling power, i is the opening number, and EMR 额 is the rated power of a single refrigeration unit. When Ci > 1, set Ci = 0.
[0067] Step S205: Turn on the refrigeration units with the number of refrigeration units turned on.
[0068] Step S206: When the boiler heating system operates independently, match the number of boiler heating units turned on for the boiler heating system according to the heat load demand, and turn on the boiler heating units with the number of boiler heating units turned on.
[0069] Specifically, in this embodiment, according to the characteristics of various energy forms in the computer room, the energy supply system of the computer room is divided into a ground source heat pump system, a refrigeration system, and a boiler heating system. As Figure 3 shown, a distributed control system can be adopted, and 1 set of independent control systems are respectively set for the above three subsystems, defined as a ground source heat pump control module 301, a refrigeration system control module 302, and a boiler heating control module 303. These 3 sets of control systems can control the subsystems to operate independently. In addition, on the basis of the 3 subsystems, a set of centralized control module 304 is set.
[0070] Among them, the centralized control module executes step S201. When the refrigeration heat release is greater than the heating heat absorption, then in winter heating, the ground source heat pump system is preferentially used to operate independently for heating. When the heat load of the ground source heat pump system cannot meet the system load demand, the boiler heating system is enabled to operate in coupling with the ground source heat pump system for heating. In summer refrigeration, the ground source heat pump system and the refrigeration system are used to operate in coupling for refrigeration;
[0071] When the refrigeration heat release is less than the heating heat absorption, then in summer refrigeration, the ground source heat pump system is preferentially used to operate independently for heating. When the cooling load of the ground source heat pump system cannot meet the system load demand, the refrigeration system is enabled to operate in coupling with the ground source heat pump system for refrigeration. In winter heating, the ground source heat pump system and the boiler heating system are used to operate in coupling for heating.
[0072] Specifically, the centralized control module collects overall data, including outdoor temperature and humidity, total power consumption of the machine room, and total cooling and heating capacity on the user side of the machine room. Data interaction is carried out with the ground source heat pump control unit, the refrigeration control unit, and the boiler heating control unit through communication, which can realize the multi-energy coupling scheduling and centralized management of each subsystem. Make the system achieve a safe, stable, energy-saving and efficient operation effect.
[0073] 1. Mode overview: The system has two modes: heating and refrigeration. The ground source heat pump system and the boiler heating system are used in the heating mode, and the ground source heat pump system and the refrigeration system are used in the cooling mode.
[0074] 2. Load prediction: For the total cooling and heating capacity on the user side
[0075] 3. Ground source balance control: According to the hourly load calculation results of HVAC throughout the year, it is known the value of the ground source heat release when the ground source heat pump system is refrigerating and the value of the heat absorption from the ground source when heating.
[0076] When the refrigeration heat release is greater than the heating heat absorption, then the ground source heat pump is preferentially used in winter heating. Only when the heat pump load cannot meet the system load demand, the boiler heating system is enabled. In summer refrigeration, the ground source heat pump system and the refrigeration main unit system are used for coupled refrigeration, and the ground source heat balance rate is adjusted to be less than 10% under the condition of meeting the demand load.
[0077] When the refrigeration heat release is less than the heating heat absorption, then the ground source heat pump is preferentially used in summer refrigeration. Only when the cooling load cannot meet the system load demand, the refrigeration system is enabled for peak shaving. In winter heating, the ground source heat pump system and the boiler heating system are used for coupled heating, and the ground source heat balance rate is adjusted to be less than 10% under the condition of meeting the demand load.
[0078] 4. Multi - energy coupling energy ratio control: Let the total demand for cooling and heating energy in the computer room be EM, and the rated load of the ground - source heat pump system be EMR 额 , the energy output from the ground - source heat pump system is EM1, the energy output from the refrigeration system is EM2, and the energy output from the boiler heating system is EM3.
[0079] (1) Based on the above, when the refrigeration heat release is greater than the heating heat absorption,
[0080] When the system supplies heat:
[0081] If EM ≤ EMR 额 , then EM1 = EM, EM3 = 0;
[0082] If EM > EMR 额 , then EM1 = EMR 额 , EM3 = EM - EM1;
[0083] When the system supplies cooling:
[0084] If EM ≤ EMR 额 , then EM1 = EM, EM2 = 0;
[0085] If EM > EMR 额 , then EM1 = EMR 额 , EM3 = EM - EM1.
[0086] Then, the ground - source heat pump control module can execute step S202 and step S203 to control the ground - source heat pump system. The refrigeration system control module executes step S204 and step S205 to control the refrigeration system, and the boiler heating control module executes step S206 to control the boiler heating system. Among them, step S202, step S204, and step S206 are parallel and are executed according to the corresponding requirements.
[0087] Specifically, in the ground - source heat pump control module, 1 ground - source heat pump + unit water - way electric valve + 1 user - side circulation pump + 1 ground - source side circulation pump are defined as 1 set of cooling - heating units, and 1 - 4 sets of cooling - heating units can be supported according to the actual situation of the project. As a whole, the system monitors the power consumption of the ground - source heat pump system KWR, the user - side cooling capacity EMR1, the user - side heating capacity EMR2, the ground - source cooling capacity EMR3 and heating capacity EMR4, the user - side supply water temperature TR1 and return water temperature TR2, the user - side supply water pressure PR1 and return water pressure TR2, the ground - source side supply water temperature TR3 and return water temperature TR4, and the ground - source side supply water pressure PR3 and return water pressure TR4.
[0088] The control method includes:
[0089] 1. Equipment modeling
[0090] Number N of heating and cooling units: Set the number of heating and cooling units according to the actual project situation.
[0091] Ground-source heat pump: Digital modeling of the equipment is carried out according to the relevant parameters of the actual equipment, mainly including the rated refrigeration power, input power, rated heating power, input power, optimal ground-source temperature, COP values at various load rates, etc.
[0092] Circulation pump: Digital modeling of the circulation pump is carried out according to the actual equipment. The main parameters include rated flow rate, head, rated power, etc.
[0093] 2. Number of operating heating and cooling units: When the ground-source heat pump system operates independently, the system automatically matches the number of operating cold and heat sources according to the heating and cooling demands, achieving the effect of efficient and energy-saving operation while meeting the energy supply requirements. When the ground-source heat pump system is under centralized control with other systems, the number of operating heating and cooling units is coordinated uniformly by the centralized system.
[0094] 3. Calculation of system average heating and cooling power and load rate: Taking 30 minutes as a cycle, the cooling and heating amounts Q1 (unit: KWH) and Q2 (unit: KWH) on the user side are collected.
[0095] Within these 30 minutes, the average required heating and cooling power EMR = (Q1 - Q2) * 2. The average required heating and cooling power for each cycle is stored, and the predicted value EMRQ of the average heating and cooling power for a certain future time period is predicted based on the historical curve. 冷热 . The prediction method can adopt machine learning. The historical data is used as training values and input into the machine learning model to obtain the predicted value EMRQ of the average heating and cooling power for a certain future time period. 冷热 . Or select from the historical data the historical average required heating and cooling power for the same time period as the time period to be predicted and with the outdoor temperature close to that of the time period to be predicted as the predicted value EMRQ of the average heating and cooling power for a certain future time period. 冷热 .
[0096] Total rated power EMR of the system 额总 = N * EMR 额 , where, under the refrigeration condition, EMR 额 is the rated refrigeration power of the heat pump, and under the heating condition, EMR 额 is the rated heating power of the heat pump;
[0097] System load rate B = EMR / EMR 额 .
[0098] 4. Calculation of the number of hot and cold units at system startup: Automatically calculate the corresponding relationship between the unit load rate and the energy consumption ratio of the hot and cold units based on the modeling data of the heat pump unit, for example, calculate the corresponding table of the unit load rate and the energy consumption ratio of the hot and cold units. As an example, let A1, A2, A3, A4, and A5 be the energy consumption ratios when the unit load rates of the hot and cold units are 20%, 40%, 60%, 80%, and 100% respectively. The specific values of A1, A2, A3, A4, and A5 can be obtained from the factory parameters of the hot and cold units. For the heating condition, the energy consumption ratio is represented by Coefficient Of Performance, COP, and for the cooling condition, the energy consumption ratio is represented by Energy Efficiency Ratio, EER.
[0099] Then, calculate the unit load rate corresponding to each opening quantity according to the heating and cooling demands respectively;
[0100] In one embodiment, the calculating the unit load rate corresponding to each opening quantity according to the heating and cooling demands respectively includes:
[0101] According to historical data, predict the predicted value of the average heating and cooling power within a preset time period;
[0102] The unit load rate corresponding to each opening quantity is calculated as: Bi = EMRQ 冷热 / (i * EMR 额 ), where Bi is the unit load rate corresponding to the opening quantity i, EMRQ 冷热 is the predicted value of the average heating and cooling power, i is the opening quantity, and EMR 额 is the rated power of a single hot and cold unit, and when Bi > 1, set Bi = 0.
[0103] Specifically:
[0104] Assume that when one hot and cold unit is turned on to meet the system load, the unit load rate is B1,
[0105] Then B1 = EMRQ / EMR 额 , but when B1 is greater than 1, then B1 = 0;
[0106] Assume that when two hot and cold units are turned on to meet the system load, the unit load rate is B2,
[0107] Then B2 = EMRQ / (2 * EMR 额 ), but when B2 is greater than 1, then B2 = 0;
[0108] Assume that when 3 hot and cold units are turned on to meet the system load, the unit load rate is B3,
[0109] Then B3 = EMRQ / (3 * EMR 额), but when B3 is greater than 1, then B3 = 0;
[0110] And so on, calculate B1, B2, B3, B4, ……, BN.
[0111] This embodiment provides corresponding calculations of the unit load factor and the number of units turned on, so as to obtain the unit load factor corresponding to each number of units turned on.
[0112] After that, according to the corresponding relationship, calculate the energy consumption ratio corresponding to the unit load factor corresponding to each number of units turned on, and select the number of units turned on corresponding to the unit load factor with the largest energy consumption ratio as the number of cold and heat units turned on for the ground source heat pump system.
[0113] Specifically, according to the above corresponding table of unit load factor and energy consumption ratio, look up the energy consumption ratios AB1, AB2, AB3, AB4, ……, ABN corresponding to the load factors of B1, B2, B3, B4, ……, BN. When the unit load factor is not in the table, the data of the corresponding energy consumption ratio can be obtained by interpolation method.
[0114] Then compare AB1, AB2, AB3, AB4, ……, ABN to obtain the maximum value. That is, the energy consumption ratios under different numbers of cold and heat units turned on can be calculated, and the number of units turned on corresponding to the maximum energy consumption ratio is used as the number of cold and heat units turned on for the ground source heat pump system.
[0115] Then execute step S203 to turn on the cold and heat units with the number of cold and heat units turned on.
[0116] Specifically, the internal start-up and shutdown sequence of the cold and heat units: Start-up: Open the unit electric valve, turn on the user-side circulation pump and the ground-source-side circulation pump, and start the ground source heat pump unit. Shutdown: Shut down the ground source heat pump unit, turn off the user-side circulation pump and the ground-source-side circulation pump, and close the unit electric valve.
[0117] In some embodiments, it also includes frequency control of the user-side circulation pump: The frequency of the circulation pump is PID-controlled according to the pressure difference of the user-side pipeline to ensure that the pressure difference of the user-side pipeline is within the target value range, and at the same time consider the minimum frequency. When multiple pumps are running, keep the pump frequencies consistent.
[0118] In some embodiments, it also includes frequency control of the ground-source-side circulation pump: The frequency of the circulation pump is PID-controlled according to the return water temperature of the ground-source side to ensure that the return water temperature of the ground-source side is within the target value range, keep the unit running efficiently, and at the same time consider the minimum frequency. When multiple pumps are running, keep the pump frequencies consistent.
[0119] In the refrigeration system control module, one refrigeration unit + the waterway electric valve of the unit + one user-side circulation pump + one cooling-side circulation pump + one cooling cooling tower are defined as one set of cooling and heating units, and M sets of cooling and heating units can be supported according to the actual situation of the project. As a whole, the system monitors the power consumption KWR of the refrigeration system, the cooling capacity EMR1 on the user side, the supply water temperature TR1 and the return water temperature TR2 on the user side, the supply water pressure PR1 and the return water pressure TR2 on the user side, and the supply water temperature TR3 and the return water temperature TR4 on the cooling side.
[0120] The control method includes:
[0121] 1. Equipment modeling
[0122] Number of refrigeration units M: Set the number of refrigeration units according to the actual situation of the project
[0123] Refrigeration unit: Carry out digital modeling of the equipment according to the relevant parameters of the actual equipment, mainly including the rated refrigeration power and input power, the optimal cooling return water temperature, the COP value at each load rate, etc.
[0124] Circulation pump: Carry out digital modeling of the circulation pump according to the actual equipment, and the main parameters include rated flow, head, rated power, etc.
[0125] 2. Number of refrigeration units started: When the refrigeration system operates independently, the system automatically matches the number of cold and heat sources started according to the cooling load demand, and achieves the effect of efficient and energy-saving operation under the condition of meeting the energy supply demand. When the refrigeration system is centrally controlled with other systems, the number of cooling and heating units started is uniformly coordinated by the central system.
[0126] 3. Calculation of the average refrigeration power and load rate of the system: Taking 30 minutes as a cycle, collect the cooling and heating amounts Q1 (unit: KWH) and Q2 (unit: KWH) on the user side.
[0127] During these 30 minutes, the average required cooling power EMR = (Q1 - Q2) * 2. Store the average required cooling power of each cycle, and predict the average cooling power prediction value EMRQ for a certain future time period according to the historical curve. 冷 . The prediction method can adopt the machine learning method, input the historical data as the training value into the machine learning model, and then obtain the average cooling power prediction value EMRQ for a certain future time period. 冷 . Or select the historical average required cooling power in the same time period as the time period to be predicted from the historical data, and with the outdoor temperature close to the outdoor temperature of the time period to be predicted as the average cooling power prediction value EMRQ for a certain future time period. 冷 .
[0128] Total rated power of the system EMR 额总 = N * Rated refrigeration power of the chiller EMR 额 .
[0129] System load rate B = EMR / EMR 额 。
[0130] 4. Calculation of the number of refrigeration units at system startup: Automatically calculate the corresponding relationship between the unit load rate and the energy consumption ratio of the refrigeration units based on the modeling data of the refrigeration unit group, for example, calculate the corresponding table of the unit load rate and the energy consumption ratio of the refrigeration units. As an example, let D1, D2, D3, D4, and D5 be the energy consumption ratios when the unit load rates are 20%, 40%, 60%, 80%, and 100% respectively. Here, the energy consumption ratio can be represented by EER.
[0131] Then, calculate the unit load rate corresponding to each opening quantity according to the cooling load demand.
[0132] In one embodiment, the calculating the unit load rate corresponding to each opening quantity according to the cooling load demand includes:
[0133] Predict the average cold power prediction value within a preset time period based on historical data;
[0134] Calculate the unit load rate corresponding to each opening quantity as: Ci = EMRQ 冷 / (i * EMR 额 ), where Ci is the unit load rate corresponding to the opening quantity i, EMRQ 冷 is the average cold power prediction value, i is the opening quantity, and EMR 额 is the rated power of a single refrigeration unit, and when Ci > 1, set Ci = 0.
[0135] Specifically:
[0136] Assume that when one refrigeration unit is turned on to meet the system load, the unit load rate is C1.
[0137] Then C1 = EMRQ / EMR 额 , but when C1 is greater than 1, then C1 = 0;
[0138] Assume that when two refrigeration units are turned on to meet the system load, the unit load rate is C2.
[0139] Then C2 = EMRQ / (2 * EMR 额 ), but when C2 is greater than 1, then C2 = 0;
[0140] Assume that when three refrigeration units are turned on to meet the system load, the unit load rate is C3.
[0141] Then C3 = EMRQ / (3 * EMR 额 ), but when C3 is greater than 1, then C3 = 0;
[0142] And so on, calculate C1, C2, C3, C4, ……, CN.
[0143] This embodiment provides a corresponding calculation of the unit load factor and the number of units turned on, so as to obtain the unit load factor corresponding to each number of units turned on.
[0144] After that, according to the corresponding relationship, calculate the energy consumption ratio corresponding to the unit load factor of each number of units turned on, and select the number of units turned on corresponding to the unit load factor with the largest energy consumption ratio as the number of refrigeration units turned on in the refrigeration system.
[0145] Specifically, according to the above corresponding table of unit load factor and energy consumption ratio, look up the energy consumption ratios DC1, DC2, DC3, DC4, ……, DCN at the corresponding load factors for C1, C2, C3, C4, ……, CN load factors. When the unit load factor is not in the table, the data of the corresponding energy consumption ratio can be obtained by interpolation method.
[0146] Then compare DC1, DC2, DC3, DC4, ……, DCN to obtain the maximum value. That is, the energy consumption ratios under different numbers of refrigeration units turned on can be calculated, and the number of units turned on corresponding to the maximum energy consumption ratio is used as the number of refrigeration units turned on in the refrigeration system.
[0147] Then execute step S205 to turn on the refrigeration units with the number of refrigeration units turned on.
[0148] Specifically, the internal switching sequence of the refrigeration unit: When starting up: Open the unit electric valve, turn on the user-side circulation pump, the cooling circulation pump and the cooling tower, and start the refrigeration unit. When shutting down: Shut down the refrigeration unit, turn off the user-side circulation pump, the cooling circulation pump and the cooling tower, and close the unit electric valve.
[0149] In some embodiments, it also includes frequency control of the user-side circulation pump: The frequency of the circulation pump is PID-controlled according to the pressure difference of the user-side pipeline to ensure that the pressure difference of the user-side pipeline is within the target value range, and the minimum frequency is considered at the same time. When multiple pumps are running, keep the pump frequencies consistent.
[0150] In some embodiments, it also includes frequency control of the cooling tower: The frequency of the cooling tower is PID-controlled according to the temperature of the cooling return water to ensure that the temperature of the cooling return water is within the target value range, keep the unit running efficiently, and the minimum frequency is considered at the same time. When multiple pumps are running, keep the pump frequencies consistent.
[0151] In the boiler heating control module, one boiler + the waterway electric valve of the unit + one user-side circulation pump are defined as one set of boiler heating units, and K sets of heating and cooling units can be supported according to the actual situation of the project. As a whole, the system monitors the power consumption of the refrigeration system KWR, the heat supply of the user side EMR1, the supply water temperature TR1 and the return water temperature TR2 of the user side, the supply water pressure PR1 and the return water pressure TR2 of the user side.
[0152] The control method includes:
[0153] 1. Equipment modeling
[0154] The number of boiler heating units K: Set the number of boiler heating units according to the actual situation of the project.
[0155] 2. The number of boiler heating units started: When the boiler heating system operates independently, step S206 is executed. The system automatically matches the number of boiler heating units started according to the heat load demand. Under the condition of meeting the energy supply demand, the effect of efficient energy-saving operation is achieved. Specifically, select the minimum number of boiler heating units that can meet the system heat load demand as the number of boiler heating units started. When the boiler heating system is centrally controlled with other systems, the number of boiler heating units started is coordinated by the central system.
[0156] 3. The boiler heating units meet the heating demand with the least number of boiler units according to the heat supply on the user side of the boiler and in combination with the rated heat supply of the boiler. When the boiler operates at full load and still cannot meet the heat supply, additional heating units are added.
[0157] 4. The internal start-up and shutdown sequence of the boiler heating units: Start-up: Open the unit electric valve, open the user-side circulation pump, and start the heating boiler. Shutdown: Shut down the heating boiler, shut down the user-side circulation pump, and close the unit electric valve.
[0158] This embodiment conducts subsystem and centralized management control for the multi-energy coupling high-efficiency computer room composed of the ground source heat pump system, the refrigeration system, and the boiler system. The control system realizes technical features such as ground source balance, climate compensation, interlock control, and energy efficiency management.
